广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.     

滥用抗生素致喉真菌病3例报告

喉部真菌病很少见,大多由口腔、咽部及鼻部真菌感染而继发。近年来,真菌病特别是深部真菌病的发病率有了明显的增加,其原因与大量抗生素的广泛应用有关。本文报告3例因滥用抗生素所致的喉真菌病,旨在使临床医生能够正确应用抗生素。1临床资料病例1:患者女,50岁。因声音嘶哑、咽     

骨科会客室

本刊:请您谈谈对骨质疏松性骨折的认识? (?)德明教授:随着社会的老龄化,骨质疏松症已经成为骨科医师日常临床诊疗工作的重要内容。除骨骼本身退化的因素外,老年人视力、听觉等感觉器官功能衰退及神经系统、运动系统功能退化,使老年人跌倒和外伤的几率明显高于年轻人,骨折往往成为骨质疏松症患者首次就诊的原因。因此在骨科的临床诊疗工作中,对于骨质疏松症性     

丙戊酸钠合并氯丙嗪治疗精神分裂症的对照研究

目的观察丙戊酸钠合用氯丙嗪治疗精神分裂症的疗效与不良反应。方法符合CCMD-3诊断标准的精神分裂症住院患者,丙戊酸钠合用氯丙嗪组(研究组)35例,单用氯丙嗪组(对照组)31例。以PANSS、CGI、TESS量表评定观察12周。结果研究组总体疗效自第2周起明显优于对照组(P<0.05),其中研究组兴奋症状分及攻击因子分自第4周起缓解明显优于对照组(P<0.05)。研究组较对照组副反应较少且程度较轻(P<0.05)。结论丙戊酸钠合并氯丙嗪治疗精神分裂症疗效肯定,安全性与耐受性较好。     

接种浓度对人骨髓基质干细胞在脱钙骨上生长和分布的影响

目的研究不同接种浓度对人骨髓基质干细胞在脱钙骨支架上生长过程及分布的影响.方法荧光活性染料DiI标记人骨髓基质干细胞,接种于部分脱钙骨支架材料上,测定细胞的粘附率;将细胞悬液浓度分别调整为20×106、10×106、5×106/mL和空白组,依次接种于同一块脱钙骨支架4个相邻象限的中心位置上.接种后第2、7 d在倒置荧光显微镜下观察材料表面的细胞分布、生长的情况,测量细胞材料面积比.结果 DiI标记的骨髓基质干细胞的粘附率为(99.9±0.2)%,未标记的骨髓基质干细胞粘附率为(99.1±1)%,两者无统计学差异(P＞0.05).不同浓度细胞的细胞材料面积比无差异(P＞0.05).结论通过DiI标记可以动态观察细胞在材料上的生长状况.20×106、10×106、5×106/mL接种浓度均能达到覆盖脱钙骨表面直接接种部位的目的.

肾移植患者血清细胞间粘附分子-1测定的临床意义

动态测定50例肾移植患者术后血清细胞间粘附分子-1（Intercellularadhesionmolecule-1，ICAM-1）的含量．结果表明，术后发生急性排鼻者，血清ICAM-1值明显高于无排异反应的病人，且在血清肌酐浓度升高前1天～2天已升高，随着排异反应的控制，血清ICAM－1也恢复至排异前水平；而环孢素A（CSA）急性肾中毒患者，血清ICAM－1值无变化．结果提示，动态观察血清ICAM－1对急性排异反应的早期诊断，疗效观察以及急性排异与CSA急性肾中毒的鉴别诊断均具有一定的临床应用价值．
